Thank you for supporting the Laboratory of Tree-Ring Research.
Your contributions help us to continue our mission as the preeminent center for the advancement of tree-ring techniques, and the broad application of dendrochronology in the social and environmental sciences. You can choose to support the LTRR through any of the following areas of research, teaching, and outreach.
LTRR Collection
The Rex Adams Endowment for the Tree-Ring Archive plays a vital role in ensuring unique and irreplaceable tree-ring specimens are protected and available for the next generations regionally, nationally, and internationally. Endowment funds help support the Tree-Ring Archive's ongoing program of experiential learning for undergraduate students, who gain hands-on training in museum-standard archival and curation practices while assisting with the survey, cataloging, rehousing, preservation, and access to wood specimens housed within the repository.

Outreach & Science Education
Our LTRR Outreach Program is the core of communicating science to a broader audience and serves as the “heartwood” of our science education program. Each year, thousands of visitors ranging from preschoolers through retirees are enriched through interactions with our researchers, docent outreach team, one-of-a-kind exhibits, lab tours, classroom visits, and the Sky Island Science Investigators field classes. Your support is vital to educating the public and fostering the next generation of researchers.

Aegean Dendrochronology Project
The Aegean Dendrochronology Project (ADP) and Interdisciplinary Chronology of Civilizations Project (ICCP) seek to provide a calendar-dated history for the rise and fall of civilizations in the ancient Mediterranean between 5000 BCE and 1000 CE. Support is requested for the annual fund for current interdisciplinary archaeological-science projects combining tree-ring dating, archaeology, and radiocarbon. Contributions to the Peter and Ellie Kuniholm Endowment for Aegean Dendrochronology are also much appreciated.

Bristlecone Pine Research
Bristlecone pines are the longest-living trees in the world. In tree-ring series spanning millennia, they hold time capsules of past environments vital to our understanding of the past, present, and future. Support is needed to continue fundamental research and student opportunities to learn more from these ancient sentinels.

Southwestern Dendroarchaeology
The history of dendrochronology is rooted in the archaeology of the Southwestern USA. It tells a story of culture and climate as relevant to current populations as it is to people of the past. Support is needed for ongoing work on chronology, climate, and people in this region.
